difunctionalization of alkenes has received considerable attention as an efficient and straightforward way to increase molecular complexity. However, examples of the difunctionalization of alkenes initiated by the intermolecular addition of alkoxycarbonyl radicals providing substituted alkanoates are still rare. Herein, we present the visible light-driven metal-free divergent difunctionalization of alkenes triggered
在最近几十年中,烯烃的双官能化作为增加分子复杂性的有效而直接的方法受到了广泛的关注。然而,通过分子间加成烷氧基羰基以提供取代的链烷酸酯而引发的烯烃的双官能化的例子仍然很少。在这里,我们介绍了在环境条件下由烷氧基羰基分子间加成引发的可见光驱动的烯烃的无金属发散双官能化。使用烷基甲酸酯作为烷氧羰基自由基的前体,并使用4CzIPN作为光催化剂,可以轻松获得具有高官能团耐受性和高官能度的各种取代链烷酸酯,包括β-烷氧基,β-羟基,β-二甲氧基甲氧基和β-甲酰氧基链烷酸酯。效率。此外,N-烷氧基叠氮盐。
